August 5 is a weirdly heavy-hitting day for talent. You’ve got the first man to ever walk on the moon, a guy who basically runs the DC cinematic universe now, and a doctor from Grey’s Anatomy who spent years teaching history before he ever picked up a script. Honestly, it’s a lot to take in for one random Tuesday in late summer.
When you look at the list of celebrity birthdays August 5, you start to see a pattern of people who are remarkably good at being "the guy." Not just famous, but the foundational types. Whether it’s Mark Strong playing the most intimidating villain you’ve ever seen or Neil Armstrong literally leaving the planet, this date produces high-achievers.
The Architect of the New DC Universe: James Gunn
James Gunn turned 59 in 2025, and the man is currently holding the keys to some of the biggest intellectual properties on Earth. Most people know him for taking a bunch of C-list Marvel characters—a talking raccoon and a tree—and making them the emotional heart of the MCU with Guardians of the Galaxy. But his journey started way back at Troma Entertainment. We’re talking low-budget, messy horror stuff.
He was born in St. Louis in 1966. He grew up in a big Irish Catholic family, and you can see that "family first" vibe in almost everything he directs. It’s never just about the superheroes; it’s about the weirdos finding each other. Right now, he’s deep in the trenches as the co-CEO of DC Studios, steering the ship for the 2025 Superman reboot. If you’re a fan of his work, you know he’s obsessed with practical effects and a killer soundtrack. That’s just his brand.

From the Classroom to Grey-Sloan: Jesse Williams
Jesse Williams is another August 5 heavyweight. He’s 44 now. Before he was Dr. Jackson Avery on Grey’s Anatomy, he wasn't even acting. He was a high school teacher in Philadelphia. He taught American Studies, African Studies, and English for six years. Think about that next time you’re watching a rerun; he actually knows the history he’s often advocating for in real life.
Williams is a massive activist. He won the BET Humanitarian Award in 2016 and gave a speech that people still talk about today. He’s not just a face on a poster. He’s also moved into producing and even Broadway, getting a Tony nomination for Take Me Out. He’s a multi-hyphenate in the truest sense.
The Chameleon: Mark Strong
Mark Strong is 62. If you don't know his name, you definitely know his face. He’s the guy in Kingsman, Sherlock Holmes, and 1917. He was actually born Marco Giuseppe Salussolia. His mom changed his name so he’d fit in better in England.

Strong is famous for being the "actor's actor." He’s close friends with Daniel Craig—they actually lived together back in the day. He’s got this incredible range where he can be a terrifying mob boss one minute and a loyal, tech-savvy mentor the next. He stays out of the tabloids, lives a quiet life in North London with his wife and two sons, and just works. Constantly.
A Moonwalker and a Disney Star
You can’t talk about August 5 without mentioning Neil Armstrong. He was born in 1930. He’d be 95 if he were still with us. He got his pilot’s license at 16, before he could even drive a car. That’s the kind of energy this day brings. He was an Eagle Scout who ended up flying 78 combat missions in the Korean War before NASA even came calling.
On the younger side of the spectrum, we have Olivia Holt. She turned 28 in 2025. She’s been in the Disney machine since she was a kid, starring in Kickin' It and I Didn't Do It. But she’s successfully made that jump to more mature roles, like in the psychological thriller Cruel Summer. She also made her Broadway debut as Roxie Hart in Chicago recently.

Why August 5 Birthdays Actually Matter
There’s this weird intersection of discipline and creativity on this day. You see it in the athletes like Ewing and Jones, and in the "creators" like Gunn and Williams. These aren't just "overnight" celebrities. They usually have a long, gritty backstory before they hit the big time.
What You Can Do Next
If you share this birthday, or you’re just a fan, here’s how to lean into that August 5 energy:
- Watch a James Gunn movie: Not just Guardians. Go back and watch Slither or The Suicide Squad. You’ll see the evolution of a guy who really cares about the craft.
- Look into the history: Read about Neil Armstrong’s life before the moon landing. The guy was a test pilot who almost died multiple times just trying to push the boundaries of what planes could do.
- Check out the "underrated" ones: Mark Strong in Our Friends in the North is a masterclass in acting. It’s worth the find.
This isn't just a list of names. It’s a group of people who, for the most part, decided to do things the hard way and ended up at the top of their respective hills. Whether it’s acting, sports, or literal space exploration, the celebrity birthdays August 5 crowd definitely leaves a mark.
